Direct answer
Valvoline’s 2025 NLGI session presented a fully LuSC-compliant high-performance biodegradable EAL grease. LuSC is the EPA’s Lubricant Substance Classification list — ingredients, not slogans. Most Indian ‘bio greases’ fail here because a non-listed EP additive or thickener sinks the whole formula.
- Valvoline’s 2025 NLGI session presented a fully LuSC-compliant high-performance biodegradable EAL grease.
- LuSC-listed EAL grease (Valvoline session, NLGI 2025) is a European vessel-general-permit pathway. Indian exporters to EU/US waters need the list and the biodegradability method, not a ‘environmentally friendly’ TDS line.
- Name the test method on any number that reaches a TDS.
- Patents and papers are prior art, not a product Lubechem sells.
- Written for Exporters selling into US waters and EU Eco-label tenders.

Literature/prior art for this note: NLGI 2025 Annual Meeting technical session — Valvoline, fully LuSC-compliant EAL grease. Read it as evidence under its own method, not as a formula you can paste onto an Indian CoA.

Lubechem will not invent a client list or a certificate. If the next step is a trial, send the duty brief. If the next step is legal clearance of a filing, that sits with a patent attorney.
What this page is for
Sharper than the general EAL article. Ingredient-list literacy sells compliance work. Images are labelled conceptual illustrations. Patents and papers are cited so you can go read them.
What the paper is evidence for — and what it is not
| Paper says | Useful to a plant | Over-read |
|---|---|---|
| A mechanism or ranking under stated conditions | Adds a test or a caution to the brief | Not a drop-in Indian SKU |
| NLGI 2025 Annual Meeting technical session — Valvoline, fully LuSC-compliant EAL grease | Read the method section before the conclusion | Do not market the DOI on a drum |
| Limited speed / load / oil | Match your duty or discard | Do not scale a ball-on-disc to a kiln girth gear |
| Additive name or treat | A screening idea | Treat rates in papers are not commercial packages |
People-first note: this is dated editorial for decision-making. It is not a scaled rewrite of the manufacturing pages, and it is not legal or certification advice.
Questions plants actually ask
Is LuSC EAL grease a drop-in for whatever we run today?
Almost never. Thickener family, base-oil viscosity, NLGI grade and additive response all have to be matched to the duty. A purge plan comes before a plant-wide switch. Compatibility charts are screens, not guarantees.
Can we put LuSC EAL grease on the TDS because a patent or paper mentioned it?
No. Patents are prior art. Papers are evidence under stated conditions. A TDS line has to be backed by a method you actually ran, on oil you actually stock, at a treat you can buy twice.
Who owns the formula if Lubechem develops it?
Ownership is the contract. The practice is independent formulation with IP transfer as scoped — not a branded additive package you can never leave. Ask for the assignment language before the first kettle.
What should Exporters selling into US waters and EU Eco-label tenders send in the first brief?
Duty (load, speed, water, temperature, relube), the current TDS and fail mode, target specs (IS / ASTM / OEM), and whether the product is sold, used in-house, or exported. Photographs of the failed component help more than adjectives.
